You are provided 3 colour bombs, so try to reach them quickly by breaking the many blockers in the way.

Look out for any potential colour bombs and try to position some candies to make them. Otherwise use the current colour bombs provided to filter out certain colours.

Then all you need to do is make 2 colour bombs, which should not be a hard task, considering only 5 colours are present on the board, and the possibility of colour-filtering from previous colour bomb(s).

You could make a colour bomb + striped candy combination, but this isn't needed as much as some other levels, and this is very hard to do. It also cripples your score, which may be lethal if you are playing this level as a mystery quest.

Instead, simply use the colour bombs in other methods, and you will not need to worry about getting three stars.
